UNITED STATES PATENT OFFICE.

ANTIRAT'ILING DEVICE.

Application filed September 19, 1921.

To all whom it may concern:

Be it known that I, REUBEN G. McCos- KRIE, a citizen of the United States, residing at Goodland, in the county of Sherman and State of Kansas, have invented certain new and useful Improvements in Antirattling Devices, of which the following is a specification.

On at least two widely used makes of automobiles there is employed a small metal clamping device known to the trade as a valve lifter lock. There are as many of these as valve push rods, eight being used in the later models.

These are a source of considerable annoyance to car owners from their continuous rattle after being in use for a short time. The noise made by them has been compared to a string of sleigh bells. Efforts have been made to overcome this by devising a new form of lock. My invention however is to be applied directly to cars now in use and without removingor changing the present looks.

The invention consists in the novel features of construction and combination of parts hereinafter described, pointed out in the claim and shown in the accompanying drawings, in which Figure 1 is a partial outline view of an automobile engine showing three of my devices in place.

Fig. 2 is a view of the valve operating means, including the valve lifter lock and myirdevice in position.

ig. 3 is a similar view at right angles to Fig 2.

ig. 4: is a section on the line 4-4 of Fig. 2.

certain amount of play and becomes noisy.

I place on the push rod a slidable bearing block 6, locked in adjusted position by a set screw 7 and a coil spring 8 is also placed on the rod and seats at its lower end on the valve lifter lock, and bears at its upper end against the block 6. It will be noted that this spring is tapered, being much larger in diameter at its lower end than at its upper end, thereby giving it a large seating capacity so that it will rest snugly and firmly on the lifter lock, and at the same time allow for a comparatively small bearing at the upper end. The particular shape of the bearing member 6 is not material.

By means of this device all noise and rattle'in the valve lifter locks is avoided.

What I claim is i The combination with a valve push rod and a valve lifter lock, of a bearing adjustably mounted on the valve push rod, and a tapered coil spring bearing at its upper end on said bearing, and at its lower end seated on the valve lifter lock, together with means for locking said bearing in position.

In testimony whereof I afiix my signature.

REUBEN G. MoCOSKR-IE.
